Driveshaft woes
<HR style="COLOR: #d1d1e1; BACKGROUND-COLOR: #d1d1e1" SIZE=1> <!-- / icon and title --><!-- message -->
Got a question for the experts. I have a 1987 v6 man. 4wd B2 that i just blew the rear driveshaft out of. It is the CV type with no U-joints. I went to a junkyard and pulled a rear driveshaft out of an 88 v6 man. 4wd as a replacement. I noticed the one I got from the junkyard was a U-joint type. I went to go bolt it up and it's about 4 inches too short. I thought they were interchangeable? Any help or knowledge would be appreciated.

Over those years, Ford used a few different transmissions in BII's. TK5, FM145, FM146, A4LD come to mind. I don't remember specifics, but I believe each of these transmissions is a different length. A driveshaft that fits between one of these transmissions and the rear end is probably not the right length for use behind one of the other transmissions. When getting a replacement driveshaft from a junkyard, you have to pay attention to which transmission was used and/or measure the replacement to see if it is the correct length.

Probably from a 1984/1985 or a custom shaft (unlikely - people usually remove those when junking a B2).

No, some year transmissions were different lengths.
What length is yours and what transmission do you have?
